[TR] 1973 Late Triumph GT6 Rear Brakes

[Joao Simoes]

Hey folks, does anyone have some advice on finding parts for a 1973 GT6 rear brake adjuster assembly?
The late GT6 Mk3 had a unique adjuster design that resides on the wheel cylinder and not at the bottom of the backing plate and no one seems to have them.
Is there some other part I can adapt to it or can I use earlier GT6 parts for it?

Thanks

John
